I had an interesting card-glitch today though nothing as costly and dramatic as 
yours Rob. 

Evenings while traveling I download from cards to my laptop, with a copy via 
Lightroom to an external drive. For this trip I had thought that I would NOT 
format the cards, but just leave the shots to accumulate; after all, my total 
for a couple of weeks is seldom more than 60-70 Gb, and with two cameras, four 
32Gb cards I figured I would have no issue. Last night, as I approached 
capacity on card #1 in body #1, I changed my mind. After downloading from both 
bodies, I formatted the cards in slots 1 and 2 on both bodies.

So today I did a bunch of shooting. Downloaded images from card #1 in body #1, 
but found nothing on card #1, body #2. Huh? I know I used body #2 at least some 
of the time! 
For some odd reason that has no apparent meaning for me, body #2 wrote only to 
card #2, bypassing the perfectly good card in slot #1. Nothing lost, but those 
images just not where I had expected them to be.
